Free web apps software for linux

Web Perl module contains a set of useful routines for many webworking purposes.

This module was primarily made for UNIX/Linux-Systems. Parts of it cannot be used on other systems. E.g. the procedures for file locking demand systems that can use symlinks. If you use the modul on systems where symlinks cannot be used, fatal errors may happen.

ABSTRACT

This perl module serves users with several useful routines for many purposes, like generating webpages, processing CGI scripts, working with XML datafiles and net-connections. It also uses own variants of routines, that was invented first in the famous libraries CGI.pm and cgi-lib.pl.

INSTALLATION

If you dont have sufficient privileges to install web.pm in the Perl library directory, you can put web.pm into some convenient spot, such as your home directory, or in cgi-bin itself and prefix all Perl scripts that call it with something along the lines of the following preamble:

use lib /home/myname/perl/lib;
use web;

NLock

This routine allows to set a filelock across NFS-boundaries. The common used perl-routine flock() fails at this point, so this routine is a useable alternative for bigger file-systems. It uses the modular functions link() and unlink() to mark a file locked. In addition to this, it also gives the locked file a counter: A file that is locked for more than $web::MAX_LOCKTIME seconds will be freed by the next process that calls NLock() on this file. A calling process gets either 0 or 1 as a return value, where 1 is returned if the file-locking was successful. 0 is returned only if the process waits for more than $web::MAX_WAITLOCK seconds or if symlink() fails.

Example 1:

$filename = "data.txt";
NLock($filename);
open(f1,"$filename");
# do something
close f1;
NUnlock($filename);

Example 2:

#!/local/bin/perl5
use web;

$stat= &NLock("jump.pl");
print "Lock: stat= $statn";
$stat= &NLock("jump.pl");
print "Lock this file again: stat= $statn";
sleep 8;
$stat= &NLock("jump.pl");
print "Lock this file again: stat= $statn";
$stat= &NUnlock("jump.pl");
print "Unlock: stat= $statn";
exit;

Web Auction is a simple auction designed for organizations or individuals who want to hold an auction.
The project is unlike Ebay in the sense that only administrators can add products. Products can have pictures, price, minimum bids, bid increments, and more.

VAS Apps consists of FTP, RSH/RCP, TELNET clients and servers packaged for VAS-enabled platforms. These tools give users the benefits of single sign-on for the more traditional remote access tools.

Clients: telnet, ftp, rsh, rcp
Servers: telnetd, ftpd, rshd

This software is derived from the apps component of Heimdal Kerberos.

This release should be considered as a beta.

A little playlist support is included. Important note: it is totally insecure, and should only by used in a limited environment.

Web Site Robot is an easy to use Web site builder with a blog tool, shopping cart, and online photo album. It is free and does not require additional software, HTML, programming, or a hosting company.
It enables secure online payments with credit cards. There is virtually unlimited storage space for HTML, documents, blogs, photos, music, videos, or any multimedia content.
Enhancements:
- The Robot is now able to discover and inform UPnP routers about its presence and the need to have a NAT port available for its Web server.
- In most SOHO environments with UPnP enabled routers, manual configuration is not needed.
- The operator just installs, registers the Robot and the Web site is online effortlessly.

Web Bench is very simple tool for benchmarking WWW or proxy servers. Uses fork() for simulating multiple clients and can use HTTP/0.9-HTTP/1.1 requests.
This benchmark is not very realistic, but it can test if your HTTPD can realy handle that many clients at once (try to run some CGIs) without taking your machine down.
Displays pages/min and bytes/sec. Can be used in more aggressive mode with -f switch.
Enhancements:
- allow building with both Gnu and BSD make
